Library /sys$common/syshlp/decset$envmgr.hlb cgui, dd options PopForm, diag switch Tgl  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Click on the button to direct MMS to use the macro definition "DIAG=1".

 Automatically generated description files will contain the following
 lines:

 .IFDEF DIAG
 DIA = /DIAGNOSTICS
 .ELSE
 DIA = /NODIAGNOSTICS
 .ENDIF

 and every compilation command will include the $(DIA) macro.

 If this toggle button is clicked on, then every compilation in the build
 will produce an diagnostics file.  If diagnostics files are produced
 during a build, and LSE is running, the user is able to do a REVIEW of
 each compilation from MMS.

 If this toggle button is off, no diagnostics files will be produced.

 Users can use the same mechanism in their own hand-written description
 files.
